Chapter 1
Introduction
Product Description A high-performance optical bench, low-noise electronics and various grating options make NIRQuest
Spectrometers the best choice for modular NIR spectroscopy. This small footprint, near infrared
spectrometer is available in several different models that cover various wavelength ranges between 900
nm and 2500 nm and as with most Ocean Optics designs can be customized for your specific application
with various grating, slit and mirror options. The NIRquest is ideal for applications ranging from
analyzing moisture content in food and beverage products to analyzing trace metals in wastewater and
laser characterization, among others.
Note
High Gain Mode is not recommended for NIRQuest512-2.2 and NIRQuest512-2.5
spectrometers, but can be used. An additional 30 minute warm-up time is necessary to
stabilize the detector response.
The NIRQuest (Near Infrared) Fiber Optic Spectrometer combines the high-performance InGaAs array
detector with the high-sensitivity NIRQuest optical bench. The NIRQuest Spectrometer and the 16-bit
A/D converter share a single housing, forming a small-footprint plug-and-play system.
The NIRquest communicates via the Universal Serial Bus (USB) connection with an external 5V power
source. A 30-pin interface provides several GPIO ports. The optional high gain mode can be used for
those applications requiring extra sensitivity.
An optional internal shutter is available on custom-configured spectrometers (INTERNAL-SHUTTER-
LRG-BENCH). This makes it easier to take dark measurements and when you need fast integration times
with the best possible signal. This optional feature is also recommended for probe-based or emissive
measurements where it is difficult to introduce a shutter into the optical path. The shutter can be added to
an existing NIRQuest for an extra charge.
Replaceable slits are offered for added convenience. Deep UV option includes purge port.
1: Introduction

About the Modular Approach
Ocean Optics fiber optic spectrometer systems are based on low-cost, modular data acquisition principles.
A typical NIRQuest Spectrometer system contains four basic elements:
The NIRQuest Spectrometer (see NIRQuest Spectrometer Models )
The Ocean Optics OceanView spectrometer operating software (see Product-Related
Documentation)
A light (excitation source) (see Accessories)
A variety of sampling optics (depending on application need) (see Accessories)
The light (excitation source) sends light through an optical fiber to the sample. The light interacts with the
sample, and the results are collected and transmitted through another optical fiber to the spectrometer.
The spectrometer measures the amount of light and transforms the data collected by the spectrometer into
digital information. Finally, the spectrometer passes that information to the operating software.
NIRQuest Spectrometer Models
The NIRQuest family of spectrometers consists of the following models:
NIRQuest512-1.7 with a detector range of 850 – 1700 nm; usable range of 900 – 2700 nm
NIRQuest512-1.9 with a detector range of 1000 – 1900 nm; usable range 1100 – 1900 nm
NIRQuest512-2.2 with a detector range 900 – 2200 nm; usable range of 900 – 2200 nm
NIRQuest512-2.5 with a detector range 900 – 2550 nm; usable range of 900 – 2500 nm
NIRQuest256-2.1 with a detector range of 900 – 2100 nm; usable range of 900 – 2050 nm
NIRQuest256-2.5 with a detector range of 900 – 2550 nm; usable range of 900 – 2500 nm

Connect Spectroscopic Accessories To find operating instructions on NIRQuest Spectrometer-compatible products such as light sources,
sampling chambers, probes, fibers or any other Ocean Optics spectroscopic accessories, check the the
Ocean Optics website at:
http://oceanoptics.com/support/technical-documents/
Chapter 1: Introduction contains a list of NIRQuest Spectrometer-compatible products. You can find
information related to these products on http://www.oceanoptics.com/.
External Triggering Options You can trigger the NIRQuest Spectrometer using the External Software Triggering option through the
30-pin accessory connector on the spectrometer. Only the External Software Trigger mode is available
with the NIRQuest Spectrometer.
The External Triggering Options document contains instructions on configuring External Triggering with
the NIRQuest Spectrometer (see
Product-Related Documentation).
Change the Slit There’s no need to calibrate your spectrometer when changing the slit, just install and start measuring.
There is one exception to this. You cannot change from a standard slit to a slit with a filter because it
changes the optical focus and wavelength calibration of the spectrometer. In this case you would need to
send the spectrometer back to Ocean Optics. A filter must be ordered for each slit (if your application
requires a filter) and the spectrometer needs to be calibrated and focused with the filter installed. This
only applies to filters installed inside the slit assembly.

Appendix A
Calibrating the Wavelength of the NIRQuest Spectrometer
This Appendix describes how to calibrate the wavelength of your spectrometer. Though each
spectrometer is calibrated before it leaves Ocean Optics, the wavelength for all spectrometers will drift
slightly as a function of time and environmental conditions.
About Wavelength Calibration You are going to be solving the following equation, which shows that the relationship between pixel
number and wavelength is a third-order polynomial:
p = I + C1 p + C2 p2 + C3 p

Calibrating the Spectrometer
Preparing for Calibration
To recalibrate the wavelength of your spectrometer, you will need the following:
A light source capable of producing spectral lines.
A: Calibrating the Wavelength of the Spectrometer
18 016-70000-000-02-201603
Ocean Optics’ AR-1 Argon lamp or HG-1 Mercury-Argon lamp are ideal for this purpose. If you
do not have an AR-1 or HG-1, you will need a spectral line source that produces several (at least
4-6) spectral lines in the wavelength region of your spectrometer.
If an order-sorting filter is installed in the NIRQuest, the XE-1 Xenon lamp is necessary to
perform the wavelength calibration.
The NIRQuest Spectrometer.
An optical fiber (for spectrometers without a built-in slit, a 50-m fiber works best).
A spreadsheet program (Excel or Quattro Pro, for example) or a calculator that performs third-
order linear regressions.
If you are using Microsoft Excel, choose Tools | Add-Ins and check AnalysisToolPak and
AnalysisTookPak-VBA.
Calibrating the Wavelength of the Spectrometer ► Procedure
Perform the steps below to calibrate the wavelength of the spectrometer:
1. Place spectrometer operating software into Quick View (Scope mode) and take a spectrum of
your light source. Adjust the integration time (or the A/D conversion frequency) until there are
several peaks on the screen that are not off-scale.
2. Move the cursor to one of the peaks and position the cursor so that it is at the point of maximum
intensity.
3. Record the pixel number that is displayed in the status bar or legend (located beneath the graph).
Repeat this step for all of the peaks in your spectrum.
4. Use the spreadsheet program or calculator to create a table like the one shown in the following
figure. In the first column, place the exact or true wavelength of the spectral lines that you used.
In the second column of this worksheet, place the observed pixel number. In the third column,
calculate the pixel number squared, and in the fourth column, calculate the pixel number cubed.

Specifications
How the Spectrometer Works Light passes through the NIRQuest Spectrometer through a fixed optical path. The optical bench of the
NIRQuest Spectrometer has no moving parts that can wear or break; all the components are fixed in place
at the time of manufacture.
NIRQuest Spectrometer with Components
NIRQuest Spectrometer Component Table
The following table describes each component in the NIRQuest Spectrometer. Items marked with an
asterisk (*) can be user-specified (consult an Applications Scientist for more information).
B: Specifications
22 016-70000-000-02-201603
1 SMA Connector Secures the input fiber to the spectrometer. Light from the input fiber enters the optical bench through this connector.
2 Interchangeable Slit
A dark piece of material containing a rectangular aperture, which is mounted directly behind the SMA Connector. The size of the aperture regulates the amount of light that enters the optical bench and controls spectral resolution.
You can also use the NIRQuest without a slit. In this configuration, the diameter of the fiber connected to the NIRQuest determines the size of the entrance aperture.
The user can change the slit. Ocean Optics also offers a range of FC connector slits in the same wavelengths, with the product code INTFC-XXX. An INTFC-KIT is also available.
3 Filter
Restricts optical radiation to pre-determined wavelength regions. Light passes through the Filter before entering the optical bench. Both bandpass and longpass filters are available to restrict radiation to certain wavelength regions.
Only Ocean Optics technicians can change the Filter.
4 Collimating Mirror
Focuses light entering the optical bench towards the Grating of the spectrometer.
Light enters the spectrometer, passes through the SMA Connector, Slit, and Filter, and then reflects off the Collimating Mirror onto the Grating.
5 Grating
Diffracts light from the Collimating Mirror and directs the diffracted light onto the Focusing Mirror. Gratings are available in different groove densities, allowing you to specify wavelength coverage and resolution in the spectrometer.
Only Ocean Optics technicians can change the Grating.
6 Focusing Mirror Receives light reflected from the Grating and focuses the light onto the CCD Detector or L2 Detector Collection Lens (depending on the spectrometer configuration).
7 InGaAs Detector Each pixel on the detector responds to the wavelength of light that strikes it. Electronics bring the complete spectrum to the software.

1 “Useable range” is defined in the context of the NIRQuest model’s detector response and its typical grating response. For example,
the 512-element detector has response at 850 nm, but grating response begins at 900 nm. The G9206 256-element detector response is sensitive to TEC temperature, and has response only to 2050 nm when the TEC is set to -20 ºC. The G9208 256-element and 512-element detector has response to 2550 nm, but the grating efficiency drops off at 2500 nm.

Appendix C
NIRQuest512-2.5 and NIRQuest256-2.5 Sensitivity
When configuring a system for operation out to 2.5µm it is important that you consider the following
details:
Short Integration Times: For the detector to be sensitive out to 2.5µm, the detector’s band gap
energy must be small. Unfortunately, this raises the absolute level of the detectors dark signal.
Typical dark signals at 400ms (NIRQuest512-2.5) and 135ms (NIRQuest256-2.5) are shown
below.
Fiber Selection: For maximum signal intensity, alternative fiber materials should be used for
wavelengths greater than 2.2µm.
